Description

Technical Field

[0001] This invention relates to the field of water cycle power generation technology, specifically a solid water cycle energy-saving power generation system. Background Technology

[0002] Currently, new energy power generation technologies mainly include wind power, solar photovoltaic power, and traditional pumped storage power generation, but these technologies all have significant drawbacks. Wind power generation relies on specific geographical conditions and needs to be built in high-wind-frequency areas such as mountains and coastlines, resulting in high infrastructure costs and some environmental damage. Furthermore, wind power generation is limited by wind speed, with an effective power generation time of only about 2500 hours per year, an energy conversion efficiency of less than 30%, and an investment payback period of 5-8 years. Solar photovoltaic power generation is also limited by weather conditions, with an effective power generation time of only about 1270 hours per year. Photovoltaic panels require a large footprint, have high maintenance costs, and low energy conversion efficiency, with an investment payback period of about 5-6 years. Traditional pumped storage power generation, while able to regulate grid peak and off-peak times, relies on large reservoirs, requires a large land area, has strict terrain requirements, and suffers from water loss due to evaporation.

[0003] The common shortcomings of existing clean energy technologies are: dependence on natural conditions (such as wind and sunlight), resulting in discontinuous power generation; low energy conversion efficiency; high construction costs and long payback periods; strict requirements for site conditions and insufficient flexibility; and the potential for large-scale facilities to impact the ecological environment. Therefore, there is an urgent need for a new type of energy storage power generation technology that is not limited by weather, has high conversion efficiency, is flexible in construction, and is environmentally friendly.

[0015] The beneficial effects of this invention are as follows:

[0016] 1. The hydraulic energy storage and circulating power generation technology of this invention replaces the traditional reservoir with a structure of a primary tower and a secondary tower. It combines the power conversion of water pump circulation and water impeller to drive power generation using the gravitational potential energy of water. The system realizes a closed-loop water circulation, with no water waste and is not affected by weather, and can generate electricity continuously for 24 hours.

[0017] 2. The water impeller of the present invention can adapt to the water flow energy. When the water flow speed is fast and the energy is large, the water impeller speed increases, and the water collection buckets move towards the edge under the action of centrifugal force, increasing their number. This allows for more full utilization of the powerful water flow energy and improves the water impeller's work capacity. When the water flow speed is slow and the energy is low, the water impeller speed decreases, and the water collection buckets gather towards the center, reducing their number. This avoids the water impeller from having to work too hard due to too many water collection buckets, allowing the water impeller to maintain a good operating state under different water flow conditions, thereby ensuring the stability of power generation.

[0018] 3. This invention limits the movement of the adjusting disc within the adjusting groove by turning the adjusting bolt, thereby limiting the maximum number of water receiving hoppers in the water impeller and thus meeting the usage requirements in different environments.

[0034] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0035] like Figures 1 to 13 As shown, the present invention includes the following embodiments:

[0036] Example 1: A solid-state water circulation energy-saving power generation system includes a wind turbine 11, a primary tower 1, one water impeller 3, a secondary tower 2, another water impeller 3, a tailrace pool 21, and a circulation pool 22 connected sequentially from top to bottom; the inner diameters of the primary tower 1 and the secondary tower 2 decrease sequentially from top to bottom; the water impeller 3 at the bottom of the primary tower 1 is connected to a first generator 12; the water impeller 3 at the bottom of the secondary tower 2 is connected to a power conversion device 23, a speed-increasing device 24, a flywheel 25, and a second generator 26; the circulation pool 22 is connected to the upper port of the primary tower 1 through a superimposed water pump 27; the water pump 27 is driven by the wind turbine 11; the second generator 26 is used for load and / or energy storage.

[0037] The wind turbine 11 generates electricity driven by wind power. The electricity generated by the wind turbine 11 drives the superimposed water pump 27 to operate. The superimposed water pump 27 pumps water from the circulation pool 22 to the top of the first-stage tower 1. The water flows down the inner wall of the first-stage tower 1, converting gravitational potential energy into electrical energy. The first-stage tower 1 becomes narrower towards the bottom, increasing the impact force of the water flow. The water flowing out from the bottom of the first-stage tower 1 impacts the water impeller 3 at the top. The water impeller 3 rotates under the impact of the water flow, driving the connected first generator 12 to generate electricity. The water flow continues to move down into the second-stage tower 2. The inner wall of the second-stage tower 2 decreases in size from top to bottom, increasing the speed of the water flow. The water flows out along the lower end of the second-stage tower 2 and impacts the lower part of the tower. The water impeller 3 is mounted on a chain, which drives the power conversion device 23 to rotate. The power conversion device 23 then drives the flywheel 25, the speed increaser 24, and the second generator 26 in sequence, enabling the second generator 26 to generate electricity. The electricity generated by the second generator 26 is used for storage and utilization. The power conversion device 23, flywheel 25, speed increaser 24, and second generator 26 can be replaced by existing generator sets, as long as the water impeller 3 drives the corresponding second generator 26 to generate electricity. The water passing through the lower water impeller 3 flows into the tailwater pool 21, and the water in the tailwater pool 21 flows into the circulation pool 22. The water in the circulation pool 22 is then pumped back into the upper port of the first-stage tower 1 by the water pump 27, and this process is repeated.

[0038] Hydraulic energy storage and recycling technology utilizes the gravitational potential energy of water combined with a hydraulic system to achieve efficient energy storage and continuous power generation. The tower height is specially designed to reach several meters to tens of meters, significantly increasing potential energy reserves. This technology forms a complete closed-loop circulation system, achieving efficient utilization of water resources. Its core advantage lies in its ability to generate electricity continuously around the clock, unaffected by weather conditions. Through the efficient conversion of gravitational potential energy into electrical energy, its efficiency is significantly superior to traditional wind and photovoltaic power generation. Furthermore, its modular tower design allows for flexible deployment and wide applicability in various scenarios such as factories and ships, without relying on specific natural terrain conditions.

[0039] Hydraulic energy storage and circulating power generation technology replaces the traditional reservoir with a structure consisting of a primary tower 1 and a secondary tower 2. Combined with the circulation of water pump 27 and the power conversion of water impeller 3, it utilizes the gravitational potential energy of water to drive power generation. The system achieves closed-loop water circulation, eliminating water waste and is unaffected by weather, enabling continuous power generation 24 hours a day. Compared to wind and solar energy, its energy conversion efficiency is as high as 87% or more, with a construction cost recovery period of only about 2 years. It also features miniaturization and modularity, allowing for flexible deployment in industrial areas, mining areas, ships, and other scenarios, filling the gap in efficient continuous power generation and miniaturized applications of existing clean energy.

[0040] Pumped-storage hydroelectric power generation fills a gap in the undeveloped clean energy sector by pumping and storing water, possessing a very broad development prospect and gradually becoming a key project in the future new energy field. The cost recovery time for a tower pumped-storage hydroelectric power station is approximately two years; for solar power, it's six years; and for wind power, it's 5-8 years. The main construction cost of a tower pumped-storage hydroelectric power generation project is the initial site construction, while subsequent maintenance costs are low, requiring no additional economic expenditure. It generates electricity frequently, has a longer lifespan, and can continuously output electricity for extended periods. The hydraulic system offers fast response, and the high-speed shaft pump requires less lubrication, reducing maintenance costs on mechanical components. Power generation using this technology produces no wastewater or waste residue that pollutes the environment, making it one of the most environmentally friendly and efficient clean energy sources in the world. Reaching international energy conservation and emission reduction standards; in recent years, the world has been continuously and vigorously developing the development and utilization of renewable resources, and the current focus of development is energy-saving and environmentally friendly power generation projects; pumped storage power generation saves water resources and solves problems such as water loss and waste; the power conversion rate is higher than that of wind and solar power generation; it is environmentally friendly and small-scale, occupies a small area, is versatile, has flexible construction conditions and no site selection restrictions, and can utilize abandoned and idle mines and mines to realize distributed power generation for enterprises, factories, industrial parks, schools and other places; among the current new energy sources, wind and solar energy are both natural resources (and renewable energy sources), but they are affected by weather and cannot achieve ideal high-quality conversion power; pumped storage power generation can achieve a conversion rate of more than 87% of traditional electricity, and the output power is considerable;

[0041] In this embodiment, the wind turbine 11 is 11500mm away from the first-stage tower 1. The first-stage tower 1 has a total height of 6000mm, an inner diameter of 1900mm at the upper end, and an inner diameter of 160mm at the lower end. The second-stage tower 2 has a total height of 10600mm, an inner diameter of 1900mm at the upper end, and an inner diameter of 160mm at the lower end.

[0042] Example 2: The water impeller 3 includes a central column 4 and water collection hoppers 5 distributed on the arc-shaped outer wall of the central column 4; a central rod 41 is fixedly connected to the front and rear ends of the central column 4; radial strips 6 are fixedly connected to the arc-shaped outer wall of the central column 4 in the front-rear direction; multiple radial strips 6 are evenly distributed on the arc-shaped outer wall of the central column 4; a ring 7 is fixedly connected to one end of the multiple radial strips 6 away from the central column 4; a sliding groove 61 is provided through the opposite surfaces of two rings 7; the sliding groove 61 extends toward the radial strips 6; a slider 62 is slidably connected in the sliding groove 61; the slider 62 is fixedly connected to the front and rear sides of the corresponding water collection hopper 5; the water collection hopper 5 is fixedly connected to the arc-shaped outer wall of the central column 4 by a tension spring 51; the tension of the multiple tension springs 51 is different.

[0043] In this embodiment, the multiple tension springs 51 are symmetrical about the central column 4; two symmetrical tension springs 51 have the same tension, and adjacent tension springs 51 have different tensions.

[0044] In this system, the water impeller 3 is located at the lower port of the corresponding primary tower 1 and secondary tower 2. One of the water receiving hoppers 5 on the water impeller 3 is aligned with the lower port of the primary tower 1 and secondary tower 2. Thus, the water flow impacting the water receiving hopper 5 drives the water impeller 3 to rotate. The number of receiving hoppers on the water impeller 3 in this system is fixed. During operation, the water impeller 3 at the lower port of the primary tower 1 and secondary tower 2 faces the problem of poor compatibility between the water flow energy and the working state of the water impeller 3. On the one hand, when the system starts, because the number of water receiving hoppers 5 fixed at the edge of the water impeller 3 is fixed and they are located at the edge, a large resistance torque needs to be overcome during startup, leading to startup difficulties and increased energy consumption. On the other hand, during system operation, the water flow from the primary tower 1... When the water flows towards the secondary tower 2, the flow velocity and flow rate change. The traditional fixed number of impact drive blades are difficult to adapt to the water flow energy under different working conditions. When the water flow energy is insufficient, too many water collection buckets 5 cannot effectively utilize the limited kinetic energy, resulting in energy waste. When the water flow energy is strong, the number of water collection buckets 5 cannot be dynamically increased, and the water flow energy cannot be fully captured, resulting in low power generation efficiency and failure to achieve efficient energy circulation between electric power-driven pumping and hydropower generation within the system. In addition, the lack of an effective mechanism to dynamically adjust the number and position of the impact drive water collection buckets 5 according to the rotation speed of the water impeller 3 makes it difficult for the water impeller 3 to maintain the optimal working state under different water flow conditions, which seriously restricts the improvement of the overall performance and stable operation of the solid water circulation energy-saving power generation system.

[0045] In this embodiment, a small number of water collection hoppers 5 are initially positioned at the edge of the impeller 3, so that some of the water collection hoppers 5 are located near the center of the impeller 3. This reduces the resistance to the rotation of the impeller 3, thus facilitating its drive. For ease of description, the water collection hoppers 5 located at the edge of the impeller 3 and impacted by the water flow are referred to as active water collection hoppers 5, while those near the center of the impeller 3 are referred to as inactive water collection hoppers 5. After the water flow impacts the active water collection hoppers 5, the active water collection hoppers 5 transmit the impact force to the ring 7, which in turn transmits the force to the radial bars 6. Thus, the radial bars 6 drive the central column 4 and the central rod 41 to rotate. The rotation of the central rod 41... The impeller 3 will drive the corresponding first generator 12 or second generator 26 to generate electricity. During the overall rotation of the impeller 3, the deactivated water receiving hopper 5 will be subjected to centrifugal force. The greater the rotation speed of the impeller 3, the greater the centrifugal force on the water receiving hopper 5, and the more deactivated water receiving hoppers 5 will move. Under the action of centrifugal force, the deactivated water receiving hopper 5 will drive the slider 62 to move away from the central column 4 along the slide groove 61. During the process of the deactivated water receiving hopper 5 moving away from the central column 4, it will overcome the tension of the tension spring 51. When the deactivated water receiving hopper 5 moves to the inside of the ring 7, the deactivated water receiving hopper 5 will be converted into the activated water receiving hopper 5. The tension of the multiple tension springs 51 is different. The higher the rotation speed of the impeller 3, the greater the centrifugal force, and the more activated water receiving hoppers 5.

[0046] Furthermore, the two centrally symmetrical tension springs 51 have the same tension, enabling synchronous activation and deactivation. This makes the water impeller 3 rotate more evenly, avoiding instability of the center of gravity and energy loss caused by bias in one direction, and improving the rotation efficiency of the water impeller 3. In addition, the number of water receiving hoppers 5 in this embodiment is customized according to the requirements and the diameter of the water impeller 3, and is not limited to the number shown in the attached figure.

[0047] In this embodiment, the water impeller 3 can adapt to the water flow energy. When the water flow speed is fast and the energy is high, the water impeller 3 rotates faster, and the water collection buckets 5 move towards the edge under the action of centrifugal force, increasing their number. This allows for more efficient utilization of the powerful water flow energy and improves the work capacity of the water impeller 3. When the water flow speed is slow and the energy is low, the water impeller 3 rotates slower, and the water collection buckets 5 gather towards the center, reducing their number. This avoids the water impeller 3 from working too hard due to too many water collection buckets 5, ensuring that the water impeller 3 can maintain a good operating state under different water flow conditions, thereby ensuring the stability of power generation. The water impeller 3 in this embodiment has high efficiency and stability, and the number of water collection buckets 5 is automatically adjusted with the rotation speed, allowing the water flow to be more efficient. Impeller 3 maintains a relatively reasonable stress state and energy conversion efficiency under different operating conditions, reducing energy loss. This adaptive adjustment helps maintain the stability of impeller 3's rotation, reduces speed fluctuations caused by changes in water flow, makes impeller 3 run more smoothly and reliably, and extends the service life of impeller 3. In this embodiment, the simplified control mechanism of impeller 3 eliminates the need for a complex external control system to adjust the number of water receiving hoppers 5. It can automatically adjust the number of water receiving hoppers 5 by relying solely on the natural physical phenomenon of centrifugal force, reducing the design and manufacturing costs of impeller 3, reducing potential failure points caused by complex control systems, and improving the overall reliability and ease of use of impeller 3.

[0048] Example 3: An adjusting groove 42 is provided inside the central column 4; an adjusting disc 43 is slidably and sealingly connected inside the adjusting groove 42; a threaded hole 44 is provided on the end face of the central column 4, communicating with the adjusting groove 42; an adjusting bolt 45 is threadedly connected inside the threaded hole 44; the adjusting disc 43 divides the internal space of the adjusting groove 42 into a plugged cavity 421 and a non-plugged cavity 422; a folding sleeve 8 is connected between the arc-shaped outer wall of the central column 4 and the water receiving hopper 5; multiple folding sleeves 8 are nested together and movably and sealingly connected; the innermost folding sleeve 8 is fixedly connected to the arc-shaped outer wall of the central column 4, and the outermost folding sleeve 8 is fixedly connected to the outer wall of the water receiving hopper 5; the innermost folding sleeve 8 communicates with the plugged cavity 421 through a liquid hole 81.

[0049] Before installing and using the impeller 3, first tighten the adjusting bolt 45. After tightening along the threaded hole 44, the adjusting bolt 45 moves along the axial direction. Tightening in the forward or reverse direction can change the direction of movement of the adjusting bolt 45. The longer the adjusting bolt 45 extends into the adjusting groove 42, the more restricted the movement of the adjusting disc 43 in the adjusting groove 42, resulting in a larger minimum space in the plug cavity 421. The plug cavity 421 refers to the cavity with the adjusting bolt 45. During the rotation of the impeller 3, the deactivated water receiving hopper 5 will overcome the corresponding tension spring 51 and move away from the central column 4 under the action of centrifugal force. Multiple folding sleeves 8 will unfold as the water receiving hopper 5 moves away from the central column 4. During the unfolding process of multiple folding sleeves 8, a negative pressure is formed on the inside, causing the liquid medium in the plug cavity 421 to flow into the inside of the multiple unfolded folding sleeves 8 along the liquid hole 81 under the action of negative pressure until the corresponding number of deactivated water receiving hoppers 5 are converted into activated water receiving hoppers 5. The adjusting groove 42 slides and contacts the adjusting bolt 45. The adjusting bolt 45 restricts the continued reduction of the plug cavity 421, making it difficult to increase the number of activated water hoppers 5. When the speed of the water impeller 3 decreases, the tension spring 51 will activate the water hopper 5, which will move closer to the central column 4 and become deactivated. Multiple stacking sleeves 8 will stack on each other, and the liquid medium inside the multiple stacking sleeves 8 will flow back into the plug cavity 421 along the liquid hole 81, increasing the space inside the plug cavity 421. In this embodiment, the more stacking sleeves 8 there are, the shorter the axial length of the stacking sleeves 8 is required to maintain the unfolding of multiple stacking sleeves 8. This makes the deactivated water hopper 5 closer to the central column 4, thus reducing the impact of the deactivated water hopper 5 on the rotational resistance of the water impeller 3. In this embodiment, by tightening the adjusting bolt 45, the movement position of the adjusting plate 43 in the adjusting groove 42 is restricted, thereby limiting the maximum number of activated water hoppers 5 in the water impeller 3, thus meeting the usage requirements in different environments.

[0050] Example 4: The water receiving hopper 5 is semi-cylindrical in shape; a tipping bucket 9 is rotatably and sealed inside the water receiving hopper 5; the tipping bucket 9 has the same shape as the water receiving hopper 5; the tipping bucket 9 is rotatably connected to the slider 62 via a tipping shaft 91; one wall of the slide groove 61 is provided with a first toothed groove 63; a rack 64 (simplified representation in the figure) is provided in the first toothed groove 63; the slider 62 is provided with a second toothed groove 65 on the side facing the first toothed groove 63; a cylindrical gear 66 (simplified representation in the figure) is rotatably connected in the second toothed groove 65 and meshes with the rack 64; the cylindrical gear 66 is fixedly connected to the end of the tipping shaft 91.

[0051] In this embodiment, a transition gear 67 is rotatably connected in the second tooth groove 65; the cylindrical gear 66 meshes with the rack 64 through the transition gear 67 (simplified representation in the figure); the cylindrical gear 66 has fewer teeth than the transition gear 67.

[0052] As the deactivated water hopper 5 moves away from the central column 4 under centrifugal force, it drives the slider 62 to slide within the groove 61. The cylindrical gear 66 inside the slider 62 meshes with the rack 64 in the first tooth groove 63, causing the cylindrical gear 66 to rotate and drive the flip shaft 91 to rotate. During the rotation of the flip shaft 91, the flip bucket 9 will flip. After the deactivated water hopper 5 is converted to the activated water hopper 5, the flip bucket 9 will completely enter the water hopper 5, exposing the opening of the water hopper 5. As the speed of the impeller 3 decreases, the activated water hopper 5 will convert to the deactivated water hopper 5. The slider 62 will slide along the groove 61 again, and the meshing of the cylindrical gear 66 and the rack 64 will drive the flip bucket 9 to flip again. After the slider 62 moves to the end of the groove 61 near the central column 4, the flip bucket 9 will completely cover the water hopper 5, thus making the flip bucket 9 and the water hopper 5 form a near-circular shape. The cylindrical shape prevents water from splashing onto the unused water hopper 5 during water collection, reducing the impact of water flow on its rotation and making the impeller 3 rotate more smoothly and stably. Furthermore, since the cylindrical gear 66 meshes with the rack 64 through the transition gear 67, and the number of teeth on the transition gear 67 is greater than that on the cylindrical gear 66, the transition gear 67 drives the cylindrical gear 66 to rotate with less effort, making the tipping bucket 9 rotate with less effort. This makes the slider 62 slide more sensitively within the slide groove 61. In this embodiment, the teeth of the rack 64, rack 64, and cylindrical gear 66 shown in the attached drawings only indicate the meshing state and do not represent the tilting angle of the tipping bucket 9. The tipping bucket 9 only needs to be positioned at the end of the slide groove 61 away from the central column 4 to open the water hopper 5, and at the end of the slide groove 61 close to the central column 4 to block the water hopper 5.

[0053] Example 5: As the slider 62 moves along the slide groove 61 toward the central column 4, the tipping bucket 9 will start to flip from the position of the water receiving bucket 5 near the central column 4.

[0054] As the slider 62 approaches the central column 4, the activated water hopper 5 will transform into the deactivated water hopper 5. The tipping bucket 9 will flip under the drive of the cylindrical gear 66. The tipping bucket 9 will flip first from the position closest to the central column 4, so that the water remaining in the water hopper 5 can flow out along the edge gap of the water hopper 5 away from the central column 4, avoiding water remaining inside the deactivated water hopper 5.

[0055] Example 6: The plugless cavity 422 is connected to the outside through a one-way air inlet 46; the plugless cavity 422 is connected to the bottom of the first tooth groove 63 through a one-way air outlet 47.

[0056] In this embodiment, the outer wall of the ring 7 is provided with an annular groove 71; the outer edge of the ring 7 is rotatably sealed to a rotating ring 72; the center of gravity of the rotating ring 72 is lower; and the top of the rotating ring 72 is provided with through holes 73 extending vertically.

[0057] When the speed of the impeller 3 increases, the slider 62 moves away from the central column 4 along the slide groove 61. The adjusting disc 43 slides within the adjusting groove 42 and compresses the plugged cavity 421, increasing the space in the unplugged cavity 422 and creating negative pressure. External gas enters the unplugged cavity 422 through the one-way air inlet 46 to replenish the gas supply. When the speed of the impeller 3 decreases, the slider 62 moves closer to the central column 4 along the slide groove 61. The adjusting disc 43 slides within the adjusting groove 42 and compresses the unplugged cavity 422, reducing the space in the unplugged cavity 422 and reducing the gas pressure within it. The air is discharged along the one-way outlet 47, impacting the first tooth groove 63 to clean impurities within it and ensure stable transmission of the rack 64. Furthermore, a rotating ring 72 is rotatably sealed to the outer edge of the ring 7. As the space within the unblocked cavity 422 increases, a negative pressure is generated in the through hole 73 on the rotating ring 72. The through hole 73 is far from the center of gravity of the rotating ring 72, and its position is always at the apex of the water impeller 3 to reduce the probability of liquid being drawn into the unblocked cavity 422, thus ensuring that only airflow impacts impurities within the first tooth groove 63.

[0058] Example 7:

[0059] The impeller includes a wheel housing 31, a rotor 32, a shaft 33, and a water bucket body 34. A trigger block 35 is provided on the side wall of the wheel housing 31. A reset strip 36 is provided at the bottom of the wheel housing 31. The rotor 32 is rotatably connected to the wheel housing 31 via the shaft 33. The water bucket body 34 is rotatably connected to the edge of the rotor 32 via a water bucket shaft 37. A limiting block 38 is fixed to the inner wall of the rotor 32 to limit the water bucket body 34 after it is unfolded. A trigger strip 39 is provided on the outer side of the end of the water bucket shaft 37. The water bucket body 34 is unfolded after the trigger strip 39 contacts the trigger block 35, and the water bucket body 34 is retracted after it contacts the reset strip 36.

[0060] The rotating wheel 32 is rotatably connected to the inside of the wheel housing 31 via the rotating shaft 33. The wheel housing 31 is a shell-shaped container for holding water, and a trigger block 35 is fixedly connected to the vertical inner wall of the wheel housing 31. Taking the movement of one of the water bucket bodies 34 as an example, the uppermost folded water bucket body 34 moves synchronously with the rotation of the rotating wheel 32. After the trigger bar 39 contacts the trigger block 35, it will be pressed and drive the water bucket shaft 37 to rotate. The water bucket shaft 37 is fixedly connected to the water bucket body 34, thus causing the water bucket body 34 to flip outward, realizing the change from the folded state to the unfolded state. After unfolding, the handle of the water bucket body 34 is limited by the limiting block 38, thereby maintaining the unfolded state of the water bucket body 34. After unfolding, the opening of the water bucket body 34 faces the water drop position, thus catching water. The water bucket body 34 realizes the conversion of gravitational potential energy to kinetic energy under the impact of the water flow. As the rotating wheel 32 rotates, the water bucket body 34 contacts the reset strip 36 at the bottom of the wheel housing 31, thereby pushing the water bucket body 34 to flip inward and reset. The end of the water bucket body 34 away from the water bucket shaft 37 will abut against the adjacent limit block 38 to achieve a limit. As the water bucket body 34 continues to move upward, the water bucket body 34 always remains in a retracted state until the corresponding trigger strip 39 is triggered again by the trigger block 35 and then unfolds. This process is repeated. During the rotation of the rotating shaft 33, it will drive the corresponding first generator 12 or second generator 26 to generate electricity. By unfolding the water bucket body 34 at the water receiving position and retracting the water bucket body 34 away from the water receiving position, the air resistance at the non-water receiving position is reduced, the rotation efficiency of the rotating wheel 32 is improved, and the structural instability caused by shaking is avoided. By reducing these effects, the rotating wheel 32 can rotate more effectively and the rotation torque is improved.
